[Outpatient PCI in France: data from the France PCI registry]. / L'angioplastie coronaire ambulatoire en France : données du registre France PCI.

Percutaneous coronary intervention (PCI) is the preferred method of revascularization for chronic coronary syndromes. Outpatient PCI has demonstrated, in addition to its reliability and safety, the comfort of patients and the reduction of costs that weigh on our healthcare systems. Nevertheless, it remains largely underutilized in France, with significant disparities between centers, particularly between private and public ones. This article provides an overview of outpatient PCI in France based on the France PCI registry and allows us to position ourselves in relation to our European neighbors.

Optical coherence tomography to guide percutaneous coronary intervention of the left main coronary artery: the LEMON study.

BACKGROUND: Intravascular ultrasound (IVUS)-guided PCI improves the prognosis of left main stem (LMS) PCI and is currently recommended by international guidelines. Although OCT resolution is greater than that of IVUS, this tool is not yet recommended in LMS angioplasty due to the absence of data. AIMS: This pilot study aimed to analyse the feasibility, safety and impact of OCT-guided LMS PCI. METHODS: This prospective, multicentre trial investigated whether patients might benefit from OCT-guided PCI for mid/distal LMS according to a pre-specified protocol. The primary endpoint was procedural success defined as follows: residual angiographic stenosis <50% + TIMI 3 flow in all branches + adequate OCT stent expansion (LEMON criteria). RESULTS: Seventy patients were included in the final analysis (median age: 72 [64-81] years, 73% male). The OCT pre-specified protocol was applied in all patients. The primary endpoint was achieved in 86% of subjects. Adequate stent expansion was observed in 86%, significant edge dissection in 30% and residual significant strut malapposition in 24% of the cases. OCT guidance modified the operators' strategy in 26% of the patients. The rate of one-year survival free from major adverse clinical events was 98.6% (97.2-100). CONCLUSIONS: This pilot study is the first to report the feasibility and performance of OCT-guided LMS PCI according to a pre-specified protocol.
